The filter has to be changed at least every 12 months, or when it has run out, whichever is sooner. An LED display in the faucet’s left handle makes it easy to tell when filter capacity is running low. A flashing light indicates less than 10 % capacity and a rapidly flashing orange light indicates 1 % capacity, meaning the filter cartridge must be changed. When the time comes to replace the filter, the display on the tap will alert you with an orange, blinking light.

The filter can be easily disposed of as normal plastics.

The filter can be easily changed simply by unscrewing it and screwing in the new filter in its place. You don’t even need to turn the water supply off.
